This beautifully restored museum is worth a visit for its wide-ranging exhibits on everything from archeology to ethnology to numismatics to colonial weaponry. The museum has a beautiful, bright inner courtyard displaying some lovely, early 19th-century furniture, as well as an ornate horse-drawn hearse. Lots of natural light illuminates the quirky, Victorian-era potpourri of natural-history exhibits, from bugs, butterflies, polymitas (snails with multicolored shells), to preserved fleas in nuptial dress, viewed under a magnifying glass. Antique buttons and buckles, pen nibs, death masks, a Masonic lodge throne in the shape of a peacock. On the historical side, there are the usual photographs of Cárdenas heroes of the wars of independence and the Revolution and a gruesome reminder of the risks rebels took, in the form of the garrote used to strangle victims to death. 

Canimar River is a Natural Park and a river, one of the deepest in Cuba, where you can sail and enjoy the exuberant vegetation and the rich fauna of the cliffs around it. The park invites visitors to enjoy its peaceful natural beauty with horse or boat rides or fishing and snorkeling excursions. The river flows into the bay of Matanzas next to the Morrillo Castle, built in 1720.

Monserrat Heights is a pleasant park that's also the site of La Ermita de Monserrat, a handsome, Colonial-Spanish style church. Built in 1875, the church is a shrine to the patron saint of Catalonians who immigrated to Cuba. This viewpoint has a spectacular view of the city and the bay, and the opposite direction is of the Yumuri River valley. There is also a snack bar in the park where you can refresh yourself.

Founded on April 6, 1863, it is one of the most renowned cultural institutions of Latin America. On the Plaza de la Vigia, the massive, white Teatro Sauto is one of Cuba's finest and best-preserved neoclassical structures. Nationally and internationally renowned figures have performed in the ballets, operas, musical comedies, concerts, variety shows and plays that have been presented on its stage. This magnificent building has excellent acoustics and was declared a National Monument.
